JOSEPH B. HERNANDEZ, OF CORONA, NEW YORK.

THREE-WAY FLOOR CONSTRUCTION.

retirees.

' To all whom it may concern:

Be it known that I, Josnrn B. HERNAN- nnz, a citizen of the Republic ofCuba, and a resident of Corona, county of Queens, and State of New York,have invented certain new and useful Improvements in a Three- VVay FloorConstruction, of which the following is a full, clear, and exactspecification. 1a This invention relates more particularly to a class ofconstruction for buildings and the like.

My invention has for its object primarily to provide a form of concreteconstruction whereby practically fire-proof and soundproof floors ofbuildings and other structures may be built at a great saving in theconsumption of cement so as to be comparatively light in weight as wellas being ca- 2@ pable of withstanding the strain of unusually heavyloads, and which is commonly known as a'three-way system. This isaccomplished mainly by providing a base plate, or supporting surface, orceiling member on which are a plurality of substantially triangularhollow blocks, or tiles, or filler members formed with upwardly projecting tapered, or cone-shaped tops, and these blocks are relativelyarranged in as spaced relation to provide approximately triangularspaces, or passages therebetween. On the tops of the coneshaped blocksis a layer of cement formed with depending triangular ribs disposed inthe passages to hold the blocks against lateral movement, and embeddedin the ribs of the layer are a plurality of triangularly disposedreinforcing bars, or rods.

A further object of the invention is to pro- 4e vide a=floorconstruction which may be used in conjunction with structures of variousclasses, and which is susceptible of being easily built.

With these and other objects in view the invention will be hereinaftermore particularly described with reference to them:- companyingdrawings, forming a part of this specification in which similarcharacters of reference indicate corresponding parts 0 in all the views,and will then be pointed out in the claims at the end of thedescription.

In the drawings, Figure 1 is a top view of the floor constructionembodying my invention showing the assembled arrangement Specificationof Letters Patent.

of the parts thereof before the cement layer is applied thereon.

Fig. 2 is an edge view of these parts of the floor construction, showingthe manner in which construction is supported between the girders of abuilding and the like.

Fig. 3 is a sectional view taken on the line IIIIII of Fig. 1, and whichalso shows the layer of cement when the floor is finished.

Fig. 1 is a side elevation of one of the hollow cone-shaped blocks usedin the floor construction.

Fig. 5 is a top plan of the block.

Fig. 6 is a section taken through the block.

Fig. 7 is a top plan of the ribbed perforated base plate.

Fig. 8 is a section taken on the line VIII-VIII of Fig. 7, and

Fig. 9 is an enlarged fragmentary view of part of the base plate.

The floor construction consists in arranging a base-plate, or supportingsurface, as 10, between the girders 11 and 11 of the room, orcompartment of the building, or structure in which the floor is laid.The base plate 10 may be of a well-known form of sheet metal havingupwardly projecting spaced parallel ribs, as 12, transversely thereof,and through the plate at closely spaced intervals between thecorrugations are a number of perforations 12 or this base-plate may beof any of the other types commonly used for this purpose. lVhen thefloor is constructed the ribbed perforated base-plate 10 serves as aceiling member on the underside of which the plaster is spread in theusual manner, the perforations 12 permitting the plaster to firmlyadhere to the base-plate, or ceiling member.

On the base-plate 10 and disposed on top of'its ribs 12 are a number ofsubstantially triangular blocks, or tiles, or filler members, as 13, allof which are preferably of corresponding formations, and these blocksare arranged in spaced relation to each other to provide a series ofapproximately triangular passages 14 therebetween. The blocks 13 may bemade of metal, tile, terra cotta, or any other suitable fireproofmaterial, and each block has a hollow, or recessed underside 15, theblocks being so disposed. that these recesses are in opposed relation tothe base plate. Each of the hollow triangular blocks 13 has an upwardlyinclined lower wall portion 16 which may be corrugated, and projectingupwardly from thls lower I wall portion is a substantially triangulartapered, or cone-shaped upper wall, or top 17 which is also preferablycorrugated to cause a layer of cement, or concrete, as will behereinafter more fully explained, to firmly adhere thereto as well aspermitting the blocks to be made of comparatively thin material withouttending to bend, or buckle out of shape under the pressure of the layerof cement, or concrete.

Disposed in the passages 14 between the hollow triangular corrugatedblocks 18 are a number of reinforcing bars, or rods 18 all of which aremade of metal in square or other forms of any desired diameters. Theserods are disposed in overlapping triangular arrangement, as shown, andthe lower rods rest upon the ribs 12 of the base plate 10 so that all ofthe rods will be spaced from the perforated surfaces of the base plateproper.

When these parts of the floor construotion are assembled in this mannera layer of cement, or concrete, as 19, ora layer of other desiredplastic material is provided by any suitable means on top of the hollowcorrugated blocks 13, the cement being applied so that the passages 14as well as the corrugations of the blocks will be filled to providesubstantially triangular ribs 20 depending from the layer for wedgingthe blocks against all possibility of accidental movement, and byentirely filling the triangular passages 14 with the cement thetriangularly disposed reinforcing rods 18 will be embedded in thedepending ribs 20 of the layer 19. The layer 19 may be of any suitablethickness to provide the surface proper of the floor, or if desired onthe top of this layer may be laid a flooring of wood, or any othermaterial, while on the underside of the base plate may be applied alayer of plaster to form a ceiling. Thus a three-way floor system whenconstructed according to my invention in buildings and other structureswill be practically fireproof and soundproof as well as combining greatstrength and durability.

In the foregoing description, I have embodied the preferred form of myinvention, but I do not wish to be understood as limiting myselfthereto, as I am aware that modifications may be made therein withoutdeparting from the principle or sacrificing any of the advantages ofthis invention, therefore I reserve to myself the right to make suchchanges as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A filler for floor constructions comprlsing asubstantially triangular hollow member having the sides thereofinclined, horizontally disposed corrugations in said sides, a coneshaped top for said member, the apex of said cone being equidistant fromthe cor- 11ers of said triangular member and rein forcing ribs in saidtop.

2. A filler for floor constructions comprising a substantiallytriangular hollow member having the sides thereof inclined, horizontallydisposed corrugations in said sides, a cone shaped top for said member,and reinforcing ribs in said top, said reinforcing ribs meeting saidcorrugations at an angle.

8. In a floor construction, supporting means, a base plate, a pluralityof substantially triangular corrugated hollow blocks arranged on thebase plate in spaced relation to provide approximately triangularpassages therebetween, said hollow blocks having cone shaped tops,reinforcing ribs radiating from the apices of the cones, the triangularblocks being so positioned upon said base plate that the apices of thesuccessive cones are out of alinement perpendicularly with thesupporting beams. 7

4C. In a floor construction, a plurality of substantially triangularhollow members having the sides thereof inclined, horizontally disposedcorrugations in said sides,

cone shaped tops for said members with re-' inforcing ribs radiatingfrom the apices of said tops, in combination with a base plate adaptedto support said hollow members, said base plate comprising a pluralityof transversely extending ribs with'perforated portions disposedtherebetween.

This specification signed and witnessed this twenty third day of AugustA. D. 1915.
